react-redux-test | understanding redux stores and react local state management

I have new to web development and is trying to learn react and redux.

I am following this tutorial https://www.youtube.com/playlist?list=PLC3y8-rFHvwheJHvseC3I0HuYI2f46oAK

As I'm trying to extend what I learned, I'm trying to list all the users (clickable), once clicked will display (expand/collapse) all the post of the user (clickable again), once post is clicked, will display (expand/collapse) all the comment on that post

APIs to use:

users: https://jsonplaceholder.typicode.com/users

posts: https://jsonplaceholder.typicode.com/posts?userId={user.id}

comments: https://jsonplaceholder.typicode.com/comments?postId={post.id}

I have added a property collapse, on the users array upon fetch for expand/collapse monitoring

My problems are:

1. On my UsersContainer component upon click on the user, the collapse property changes (see on console), however the SampleContainer component didn't hide/show
2. On the tutorial, he said that to change the state we should/must use the action/reducer (forgot the timestamp). Since this is additional property on the array is it ok if I update state on the handleClick function? If no, please give me idea on how to implement this kind of action/reducer.

below is my UserContainer.js
